Various plant fossils from various places

[Monica]

Hello again!

 

I'm almost ready to label my Carboniferous fossils, and since I know pretty much nothing about plants fossils, I was hoping to get some help 

 

Specimen #1 from Pennsylvania, USA:

 

Specimen #2 from Illinois, USA - each half of one nodule:

 

Specimen #3 from New Brunswick, Canada:

 

Specimen #4 from New Brunswick, Canada:

 

Specimen #5 from Poland:

 

Specimen #6 from England:

 

Thanks in advance for your help!

The first looks to be from St. Clair, and the nodule from Mazon Creek. Can’t help with the IDs though. Good luck

1. Alethopteris, serlii ?

2. Pecopteris, miltoni ?

3. Mariopteris, decipiens ?

4. Mariopteris?, sp.

5. Mariopteris?, sp.

6. Mariopteris?, sp.

 

First three I'm not sure of species. Would need a very detailed image of venation and other features. Last three I'm not sure of genus -- best guess.

not sure, but for 5 and 6 maybe Alethopteris sp.????

For #5, no. Alethopteris has pinnules that are attached to the rachis along the entire basal length. It is for this same reason that it's probably not Mariopteris either. I can't see enough detail in the photo of #6 so my guess is based on general form. I'm probably wrong on the last three, and I may wrong on the species of the first three. I am also using older nomenclature because I'm not familiar with the new as I took a 10-year break from the hobby.

Okay ;on the picture I thought the pinnules were attached (at the left end) . if not, maybe Sphenopteris ?

Alethopteris has ALL the pinnules attached to the rachis along their entire length. Sphenopteris is a possibility.
